Setting classpath for a JAR

Question

I have a standalone java project. I have performed a maven clean install. I now go into the target\\classes folder via command prompt and set all the required files in class

Answer 1

It seems -cp and -jar are incompatible. You need to put the classpath in the manifest

See http://docs.oracle.com/javase/tutorial/deployment/jar/downman.html

If you want maven to automatically update the classpath, see: -

Answer 2

When you use -jar this is the sole mechanism setting the classpath for the program.

You must either have all the jars you need listed in the Class-Path line in the manifest (which implies they need to be findable in the local file system) or create a custom class loader capable of locating the jar you need.
